OUR ORIGIN
Realizing Fusion Energy
A project launched by determined researchers has brought together private
companies, giving rise to the power generation
demonstration initiative, “FAST.”
Starlight Engine is responsible for advancing the FAST project—
and for driving the realization of commercial power plants
and their integration into society beyond it.
With our mission, “Bringing fusion energy to the world,”
we take on a frontier yet unexplored by humanity—
and we will make it a reality.
OUR ROLE
From Research to Real-World Deployment
Fusion shouldn’t stop at the lab. We bring it into the real world—delivering clean power through fully operational plants.
Integration of Plant Technologies
We bring together all the critical technologies needed for power generation—fuel, fuel cycles, energy conversion, as well as safety and maintenance—into a unified system.
Building a Japan-Led Industry
By building fusion power plants in collaboration with industry, government, and academia, we will establish a strong supply chain and scale globally as a world-class industry originating from Japan.
OUR TECHNOLOGY
Compact, complete —
and closer than ever
FAST will extract fusion energy from burning plasma and demonstrate electricity generation. As the world’s first project to comprehensively solve and validate both plasma sustainment and complex engineering challenges, FAST stands at the forefront of fusion innovation.
Adopting Next-Generation Technologies
At FAST, we actively integrate advanced technologies that have yet to be fully realized in fusion development—including high-temperature superconducting (HTS) coils, low-activation materials, fuel breeding blankets, energy conversion and heat utilization systems, and neutron application technologies. By collaborating with leading private and public organizations both in Japan and abroad, we are pioneering bold new approaches to the industrialization of fusion energy.
The Potential of Compact devices
The tokamak developed by FAST offers high design flexibility and easier cost management due to its compact footprint. Its adaptable platform makes it the ideal environment for testing and improving critical components like breeding blankets and divertors. This flexible approach allows us to fully validate the integrated systems required to bring small-scale, commercial fusion plants to life.
Partnering with Communities
The site for FAST will be chosen following a nationwide public bidding process. Guided by total transparency and open dialogue with local residents, we are committed to developing fusion energy with the highest safety standards. By establishing a new center for research and building an advanced industrial supply chain, we aim to make the host region a cornerstone of future innovation.
Broader Impact
FAST is a device designed to conduct integrated technological testing regarding burning plasma and energy generation. Beyond advancing tokamak-type fusion development in Japan, it contributes to the safe and accelerated progress of various other fusion modalities being developed worldwide.
